Using 16 KHz sounds
by Malay Thakershi 25 Feb '11

25 Feb '11

Hello, I use Cepstral in my mod_managed FS application. I mainly use Session.Speak and PlayAndGetDigits in my code to play WAV / audio text. When I started using FS and got a stable program running, I used Cepstral Allison 8 KHz voice. But frequently I get choppy type of sound. Earlier it was acceptable but now some callers seem to have difficulty understanding the call audio. Would it help if I get 16 KHz sounds / Cepstral license? What are changes I would need to make? Thank you for any help. Malay Thakershi

ESL in Delphi/Pascal
by Dave Bracken 25 Feb '11

25 Feb '11

Can anyone help me to figure out how to use the ESL in Delphi? We have tried compiling the files in VS2008, and it produces a .lib file and some .obj files, but none of which can be linked into delphi. I do not know hardly anything about C, so i am kinda of flying blind here. Any help would be very greatly appreciated. DelphiGuy

Receive order guarantee for bgapi command replies over ESL?
by Mauritz Løvgren 25 Feb '11

25 Feb '11

Hi, Are replies for bgapi commands sent back to an inbound socket connection in the same order as the commands were sent? Example: sending 10 bgapi messages from client to freeswitch socket with no delay inbetween. Will the response for those command messages be sent back by freeswitch in the exact same order as their commands were received, or should one wait for each reply before sending a new bgapi command to be sure one gets a reply for the correct command? If there was an option of providing a UUID (or sequenceId) for the command, it would be easier to match the reply with the request upon receival, but this doesn’t seem to be possible with the current implementation? Regards, Mauritz Lovgren Systems Architect IPLink Inc.

Re: [Freeswitch-users] Message Playback Stops
by Michael De Lorenzo 24 Feb '11

24 Feb '11

Is there some place where I can get more detailed log information on this? I thought that streamFile was a blocking operation (the next statement wouldn't be executed until playback was completed), is that not the case? Is there a difference in terms of performance with Freeswitch for Lua versus SpiderMonkey? Am I misreading the log? > > > *2011-02-21 17:23:09.077014 [NOTICE] switch_cpp.cpp:1181 Playing file: > /usr/local/freeswitch/* > *recordings/messages/16c0f890_**c35e33c0_777973.wav* > 2011-02-21 17:23:09.077014 [DEBUG] switch_ivr_play_say.c:1186 Codec > Activated L16@8000hz 1 channels 20ms > 2011-02-21 17:23:19.417631 [DEBUG] switch_ivr_play_say.c:1515 done playing > file > 2011-02-21 17:23:19.417631 [NOTICE] switch_cpp.cpp:1181 !!!!!

Using outbound Event Sockets versus using embed language scripts
by Herman Griffin 24 Feb '11

24 Feb '11

Unless I'm complicating things, it seems like a drop to write outbound event sockets apps versus writing embedded language apps. However, I'm interested in writing event sockets apps because I can see an advantage in being able to load balance the app by running you app behind a load balancer. One simple thing that I am trying to accomplish is collecting digits and doing something useful with string of digits that have been collected. My first attempt at this is to use the play_and_get_digits dptool, but I don't now how to pull data from stored variable so that I can use in the script. I slightly modified the freeswitch.git/libs/esl/perl/server2.plscript by adding this line: $con->execute('play_and_get_digits', '2 5 3 7000 # ${base_dir}/sounds/en/us/callie/conference/8000/conf-pin.wav /invalid.wav foobar \d+' ); The next thing that I'd like to do is grab the value in foobar is use it in the perl logic. Can someone lead me to the next step? Does anyone with experience with event socket apps and embedded language apps have some useful information about their preferred path? Thanks, Herman

play media
by Jason b.a 24 Feb '11

24 Feb '11

coz i need freeswitch only for media processing, i dont want to have a direct SIP connection between user and Freeswitch, so the application server can handle the call using SIP, and using the event socket, it can ask freeswitch to play prompt, or collect digit and return it to the application so the application according to the digits can bridge the call. is it possible ? and how freeswitch can play RTP to the caller ?

guys in this case: sip caller -------Sip-------- Application server -------socket------- FreeSWITCH in this case how freeswitch is going to play media (RTP) for the sip caller, if i am only using the socket interface of freeswitch. Thx in advance !

Hi, I tried FreeSWITCH Version 1.0.head (git-f5dafc9 2011-01-21 23-42-30 +0100) FreeSWITCH Version 1.0.head (git-06988e1 2011-02-20 15-10-02 -0600) originate user/1000 &echo got this: INVITE sip:tbskvnyi@192.168.7.2:61901 SIP/2.0 Via: SIP/2.0/UDP 192.168.7.2;rport;branch=z9hG4bK0USe34K3r46gF Max-Forwards: 70 From: "" <sip:0000000000@192.168.7.2>;tag=cZt7ZSBZjQK3H Remote-Party-ID: <sip:0000000000@192.168.7.2>;party=calling;screen=yes;privacy=off And some versions of Xlite4 fails to respond to this originate {origination_caller_id_name=xxx}user/1000 works.
